A patent filed by Sony suggests that the company may be looking for backward compatibility on new consoles. The recently published patent, originally filed in November 2016, entitled "remastering by emulation". He describes a method for playing old games by remastering ancient textures on the fly.
Eurogamer reports that the full application explains how to use the "existing software" files to replace them with higher resolution resources, which allows the game to use the same framework while restoring textures or files more aesthetic audio. The result would be essentially the same as that of many remastered games that we saw with higher textures, but with much less work for developers.
"The original software is then read on the upper resolution screen, with active calls (such as textures) being intercepted, identified, and the data structure entered to retrieve the original". remastered asset having a corresponding identifier ", indicates the application. "The remastered asset is then inserted on the fly in the presentation of the game."
It is difficult to say how this technology could manifest itself. Sony may be looking forward to the next generation of consoles such as the PS5 and is considering the possibility of backward compatibility, or even the technology currently being applied to remasters.
Sony has shown its disinterest for compatibility with earlier versions. He introduced the PlayStation 3 with an upward hardware-based compatibility, but then dropped it to later models. On PlayStation 4, this feature has never been available, but relies on services like PlayStation Now and standalone reissues.
Jim Ryan, director of PlayStation Europe, said last year that backward compatibility was "one of those features that is in great demand, but not really used." Its competitor, Microsoft, introduced software-based backward compatibility in 2015 and has since been developing a growing list of titles available. At the time, Sony's former director, Shuhei Yoshida, had said that development would not change his approach.
"Backward compatibility is difficult," Yoshida said. "I will not say we will never do it, but it is not an easy thing to do, if it were easy, we would have done it.
